Create a Design: 2d and 3d designs of a mobile changing unit

Hi Freelancers, We need some designs for a customer brief. We create accessible changing units and have a live project to create a personal family unit. We have decided on a base trailer chassis and can provide a manufacturer drawing of this. We will then need our designer to work with us to put a pod (made from sandwich panels & aluminium extrusions) on our chosen chassis and to outfit it with the items that the customer has requested. We can send pencil sketches of what we have in mind and provide dimensions of the unit and some of the equipment that goes inside. The base trailer (see uploaded images) will dictate the footprint of the unit. The front of the unit can be fibreglass nose cone. The walls and ceiling will be made from Ecofont sandwich panels. The rear is an opening tailgate which allows access when the trailer is lowered to the ground (see video link for hydraulic operation of trailer [login to view URL] ) To start with we would like our design to focus on the fundamental elements of the build, externally this will be the size and shape of the unit (see 2d trailer design for footprint), the walls of the unit are to be 213cm or 7ft high and the unit will feature a large opening tailgate (see pencil sketch) a skylight towards the front and two opening slide windows towards the rear. The front and roof are yet to be designed but our concept is for a smooth rounded front similar to the Debon c700 range, however as our ceiling track hoist is rectangular we would need the styling of the front nosecone & roof to reflect this although it could house a service area. Internally the USP of our builds is an adult sized changing bed (see astor bannerman, presulit) and a xy or h ceiling track & hoist mounted on pillars in each corner (opemed). Once we have worked with a designer to create the basic external and internal designs we would like to colloborate closely to include more specliast equipment inside the unit (lighting, sink, shower head etc) but intitally we are looking for basic concepts of the inside and outside of the unit. It is a certainty that we will require more designs of this nature in the near future and hope to build a relationship with a designer who is able to effectively translate our specifications into visual models for our clients to view. Thank you for for your interest, we look forward to working with you.
